.. ELECTRICAL CONDENSER.

To all whom it may concern:

Be it known that I, MARIUS LATOUR, a citizen of France, and resident ofParis, France, have invented certain new and useful Improvements inElectrical Condensers (for which I have filed an application in Francefiled September 5, 1917, patented May 16, 1919), of which the followingis a specification accompanied by drawings.

It is the object of the present invention to secure capacities shuntedby an extremely high resistance that may be readily installed inapparatus that is not bulky. Such capacities may be utilized, e. g., inwireless telegraph apparatus in which the receivers and the vacuum tubeamplifiers utilize 10w capacities which must be shunted by a resistanceand which must be preferably reduced to thesmallest possible dimensions.

My invention is illustrated by Way of example in the accompanyingdrawings in which Fig. 1 shows the plates and assembling means.

Fig. 2 is a section through my assembled condenser taken on lines IIII.of Fig. 3.

Fig. 3 is a plan view of the assembled plate and high resistance shunt.

Fig. 4 is an end view of the same.

The core of the condenser is composed of two pairs of brass plates; eachpair comprising, as shown in Fig. 1;

A plate 1 perforated by a smooth hole 2 and a tapped hole 3 into which ascrew threaded rod 4. is soldered;

7 the diameter of hole 6 is equal to that of hole 2' and the diameter ofhole 7 is sli htly larger than the exterior diameter 0 the screwthreaded rod.

40 i The cores are assembled in the manner illustrated in Fig. 2. Theplates 1 are inside and are separated b one or a plurality of sheets ofmica 13, or y any other dielectric of a sufficient thickness to give thedesired capacity. The plates 5 are on the outside.

A leaf of paper suitably impregnated with a material of the desiredconductivity has each of its ends clamped between plates 1 and 5 asshown in Fig. 4, the two plates comprising each electrode and serving asclamping members for the ends of the paper leaf. The assembly 5 ispressed together A plate 5 perforated by two holes 6 and v by means offour nuts 9 that may be screwed on the ends of the two threaded rods.The, threaded rods are suitably insulated by means of the bushings 10(Fig. 2).

The binding posts 11 of the condenser are held fast by the nuts 9. Thecompression of the assembly causes the plates 1 and 5 to have the sameelectrical potential.

The condenser thus assembled may be placed within a protective casing 12which may be filled with an insulating material.

Having described my invention, what I claim is:

' 1. In combination, a first group of condenser'plates, a second grou ofcondenser plates, dielectric 'rnaterial said groups from each other, aclamping plate associated with each group, a conductive member havingone of its ends inserted between a plate of said first group and itsassociated clamping plate and having its other end inserted between aplate of said second .group and its associated clamping plate and meansfor clamping all of the plates, the dielectric and the ends of saidconducting member together.

2. The'combination of two pairs of conductive plates, a strip of highresistance conductive paper bent into U shape, one end of said paperbeing fitted between the plates of one pair and the other end betweenthe plates of the other pair and a dielectric between said pairs.

3. The combination of two pairs of conductive plates, a strip of highresistance conductive paper bent into U shape, one end of said paperbeing fitted between the plates of one pair andthe other end between theplates of the other pair and a dielectric between said pairs andclamping means for holding said plates together.

4. The combination of two pairs of conductive plates, a strip of highresistance conductive paper bent into U shape, one end of said paperbeing fitted between the plates of one pair and the other end betweenthe plates of the other pair and a dielectric between said pairs andclamping means for holding said plates together and a casing enclosingthe plates and the resistance.
